: Hello...I just found this website and am not sure if I'm in the right category or not, but I'm wondering if : anyone knows of anyone else who might have a similar condition. My dad has some sort of food allergy: or food intolerance...we're not sure what it is and neither are his doctors. For the past six or seven years,: he has had periodic attacks where he wakes up in the middle of with severe stomach cramps, : passes out, then either vomits or has severe diarrhea. Afterwards he is completely wiped out. : It happens very sporadically, and it appears to happen after eating certain types of foods, but we don't : know until it happens. He's had this happen with cayenne pepper, Chinese food, Fritos, once or twice : with hamburgers, and sometimes we just don't know. It's happened at home, in restaurants (very scary : and embarrassing for him) and when he's been away on vacation. We never know when it is going to: happen and these attacks have become more and more frequent. He's very nervous about eating: anywhere but at home. He's had allergy tests, but has not been diagnosed with any food allergies at all. : His doctors have told him to avoid eating those foods, but that really doesn't help much since we : never know what foods will trigger attacks. No one seems to be able to diagnose him. He's been: to an allergist, a gastroenterologist, and his regular physician. It's really scary for both him and for: us, his family, so we are seeking help. If anyone knows of ANYONE at all who has experienced : anything remotely like this, please post! Thank you so much for any help!

It may not actually be a food allergy. It may be an allergic reaction to a food additive.I have a Problem with certain types of foods such as hamburger.I can only eat the kind that has no additives,he may be allergic to msg, since you say that he has a reaction to chinese food.I would like you to know that I'm not a doctor or an expert,but I myself suffer from severe allergies.I would suggest eating more of a natualistic type diet.(free of additives and pestacides)organic fruits and veggies.I know thats easier said than done but it may help him.I was told by my doctor that many people who have allergies never find out what they're allergic to.I would find a good and reputable health food store in your area and learn more about natual foods.I wish your dad the best of luck!I truly know what its like to suffer from this type of thing.
